Title: QSO Feedback in Action: Ionization and Dust in the Wind

Abstract: GMOS/IFU observations of six nearby mergers (Rupke+Veilleux 2012) reveal massive, wide-angle, kiloparsec-scale outflows, whose velocities are highest in those systems hosting a QSO. Though the present data provide important constraints on the properties of these winds, we do not yet know how the QSO winds connect to the narrow line region (NLR), exactly how dusty the winds are, or the ionized gas extinctions necessary to exactly measure outflowing gas masses. We propose to observe five of these six systems with the GMOS IFU at bluer wavelengths to measure [O III], Hbeta, and Hgamma. We will use these data to outline the NLR and compute the extinction in the ionized gas. This will provide important constraints on the physical mechanism behind the QSO winds, and constrain the dust and ionized content of the outflow. We will compare our results to data from an extensive multiwavelength campaign of QSO winds.
